    背景
    背景
    L-精氨酸在调节免疫系统方面发挥关键作用 (1-3)。在炎症、癌症和某些其他病理状况下,骨髓细胞分化被抑制,导致出现不成熟的骨髓细胞异质群体,称为骨髓源性抑制细胞 (MDSC)。MDSCs 被募集至癌症相关炎症的位点,并表达高水平的精氨酸酶-1 (4)。精氨酸酶-1 催化尿素循环的最后一步,即将 L- 精氨酸转化为 L-鸟氨酸和尿素 (5)。因此,MDSC 可增加 L-精氨酸的分解代谢,导致癌症炎症微环境中 L-精氨酸的耗减 (4,6)。左旋精氨酸的减少会抑制 T 细胞增殖和功能,因此导致肿瘤进展 (4,6)。精氨酸酶-1 引起了研究人员的极大兴趣,这些研究人员正在寻找治疗靶标以抑制 MDSCs 在癌症免疫治疗中的作用(7)。此外,研究表明,精氨酸酶-1 可将原发性肝细胞癌 (HCC) 与肝脏中的转移性肿瘤区分开来,表明其在 HCC 诊断中可作为潜在生物标记物的价值 (8,9)。 1.Albina, J.E. et al.
